Pincers.
Background technology
Vacuum precision foundry furnace is using the principle of electromagnetic induction and heating effect of current under the conditions of vacuum atmosphere to crucible
The smelting equipment that middle billet material is heated and solidified.It melts out the steel come and may be directly applied to space flight, aviation, vapour
The high-end fields such as vehicle, nuclear power, vacuum precision foundry furnace generally use multi-chamber structure, main body include working chamber, ingot casting room, charging
The mistake that base material metal is fused into the more pure liquid metal of composition by induction coil heating is completed in room etc., wherein working chamber
Journey；Ingot casting room can dispose the solidification of different mold progress metal liquids according to the difference that melting requires；Feed compartment is in melting
It needs to feed under conditions of not destroying working chamber's vacuum in journey.
By the charging work of feed compartment completion smelting period, traditional feed way is for the charging of vacuum precision foundry furnace,
The material rod cavity body for clipping base material is subjected to vacuumize process with clamp, then opens the balance between connection working chamber and feed compartment
Valve makes the vacuum pressure in two spaces reach consistent, and to can just open isolation gate valve between the two, it is dynamic to complete charging
Make, masterbatch completes fusing and casting work in working chamber, waits casting to terminate to feed by feed compartment again, progress in cycles
Charging-melting-is come out of the stove action.
Crucible lining is replaced in scene again in more than ten stove blank of melting, due to need to often replace smelting steel grade, causes on the one hand
It is being changed without crucible lining, the blank of melting before can pollute new steel grade, on the other hand in the crucible that more renews
Lining, then need vacuum breaker to operate, and waits for that vacuum degree drops to properly, opens working chamber's door, and needs to reduce until crucible temperature
Just crucible lining is taken out with proximity gloves by employee afterwards and is operated, is reloaded into after new crucible lining and working chamber is taken out again very
Sky reaches the vacuum degree of job requirement, if this results in the purity of each matallurgical products impacted while replacement crucible lining needs
Waiting vacuumize it is long with temperature fall time, increase hot investment casting stove smelting time, lower production efficiency.Therefore,
How a kind of hot investment casting stove crucible lining clamp is provided, product purity is not only improved, but also vacuum breaker can be reduced, vacuumize, cool down
Stand-by period problem, saving hot investment casting stove stand-by period become those skilled in the art and urgently solve to improve production efficiency
Important technological problems certainly.
Invention content
In view of the above problems, the utility model provides a kind of vacuum precision foundry furnace crucible lining clamp.It is main
The technical issues of solving product purity, working chamber's vacuum breaker, vacuumizing with the crucible lining cooling stand-by period.
The technical solution of the utility model：A kind of vacuum precision foundry furnace crucible lining clamp, including driving shaft, follower lever
And crucible lining, driving shaft are fixed on holder, which is characterized in that holder be equipped with butt hole, driving shaft by bolt with it is right
Hole is connect to be fixedly connected, follower lever is made of short connecting rod and long connecting rod, holder and the short connecting rod one end hinge connection that can be rotated upwardly and downwardly,
The short connecting rod other end is bolted long connecting rod one end, and long connecting rod is bolted clamp lower plate, under the long connecting rod other end
By bolt connecting bushing clamping jaw, bushing clamping jaw concave surface matches realization with convex surface on crucible lining and clamps for end face.
Described driving shaft one end is equipped with cylinder piston rod.
The crucible lining top is provided with liner groove and forms convex surface, and then realizes bushing jaw end in face of crucible lining
It clamps and releases.
The intersection point of short connecting rod and the holder is follower lever intersection point, the two neighboring follower lever intersection point and the bracket holes
Line between angle be follower lever angle, and each follower lever angle is respectively less than 180 °.
Angle is formed between the short connecting rod and the long connecting rod and is less than 80 °.
The utility model has the beneficial effects that：The utility model crucible lining is matched with clamp instead of the prior art
It is middle to take out crucible lining with hand.Driving shaft is adjusted by cylinder piston rod moving up and down, may be implemented and driving shaft when use
The follower lever connected by connector is moved up and down around holder, realizes clamping and releasing for bushing clamping jaw and crucible lining.Work
When making, bushing clamping jaw is put at the gap between heating coil and crucible lining by adjusting driving shaft, then transfer to crucible
The lower edge of liner makes the bushing clamping jaw on follower lever hook the groove upper edge of crucible lining around rear adjusting driving shaft, finally by
Crucible lining is taken out in upper lift, is smelted in this way per stove and replaces crucible lining and do not need vacuum breaker with regard to replaceable new base material, no
It needs to wait for crucible lining temperature reduction, i.e., can work under vacuum, therefore, improve the purity of product, reduce broken
Vacuum vacuumizes, cools down the stand-by period, to improve work efficiency.The driving of driving shaft whole process is all to pass through cylinder piston rod
It automatically controls, it is rapid and efficient.Bushing clamping jaw is connect with long connecting rod with bolt, easy to disassemble and repair.
